BURNER SPECIFICATION forming part of Letters Patent No. 294,409, datedMarch 4=, 1884.

' Application filed July 2,1883. (No model.)

To rtZZ whom it may concern:

. Be it known that I, IRA W. SHALER, of Brooklyn, in Kings" county, andthe State of New York, have invented a certain new and 5 usefullmprovement in Burners, of which the following is a specification.

The object of my improvement is to make a burner produce a bettercombustion, and hence-a more desirable flame.

The improvement will first be fully described, and then will be pointedout in the claims.

In the accompanying drawings, Figure 1 is a central vertical sectionof alamp-burner embodying my improvement, and Fig. 2 is a perspective Viewof the deflector thereof.

Similar letters of reference designate corresponding parts in bothfigures.

This burner is of the kind known as an It has an annular wick tube, A,consisting of an outer wall, a, and an inner wall, (1, preferably madeof sheet metal. This wick-tube is designed to be used with a flat wick;hence, while it is of annular form throughout a large part of its lengthfrom the tip or upper end downward, yet at the bottom it is of V shape.The wick is inserted at the bottom, and as it ascends toward the tip itis bent into circular form. Near the bottom 0 the wick-tube is providedwith wick-adjusting inclosed by the inner wall of the wick-tube.

D designates a deflector consisting of an annular piece of metalsupported above the tip of the wick-tube, and having a flange or petticoat, 6, extending downwardly from it. The

annular part of this deflector preferably extends slightly upward towardthe inner edge,

so as to beof conoidal form. As shown, itsinner circumference isslightly larger than the outer wall of the wick-tube. The flange orpetticoat e is scalloped at the lower edge, or,

in other words, has notches in its lower edge. The lower end of theflange -or petticoat extends below the tip of the wick-tube. A flange or,petticoat having openings or holes in positions corresponding to thenotches of the flange or petticoat shown, and having a continuous loweredge, may be used, if preferable.

flat-wick burner.

As here shown, the deflector is supported on a" perforated sheet-metalcylinder, E. At the lower end this cylinder has aninternallyscrew-threaded collar, E, studded with perfo- 'a chimney whichis contracted in size, above the wick-tube. I find, however, that I canuse with my burner a chimney which ismuch-shorter. The collar Eof thecylinder Escrews upon ascrew-threaded boss, (1, extending fromthe body Bof the burner around theouter wall of the wick-tube. The collar can beraised or lowered by turning it around, for the purposeof adjusting thedeflector relatively to the wick-tube. .Air passes through theair-distributer or draft-plate c to the space inclosed by the innerwall-of the wick-tube, and air passes through the cylinder E and theperforations f of the collar E to the outer side of the wick-tube. Muchof the air which enters the cylinder E passes through the petticoat ofthe deflector D before reaching the flame. By passing through thenotches or openings of the petticoat, the air is broken up into manycurrents. These currents, impinging against the flame, cause it toassume a fluted form and produce a very effective combustion. Theadjustability of the deflector enables me. to regulate the size of'theflame. The top of the deflector causes all air reaching it to impingeupon the flame under uniform conditions, and renders the flamesymmetrical in form. There may be a perforated tube, G, fitted into theinner wall of the wick-tube. Such a perfo- The chimney used with theburner may rated tube will divide into small jets much of the air whichpasses through the inner wall of the wick-tube to the flame, and therebyfacilitates its combination with the flame. I may embody the sameprinciples of deflector in a The central opening will,

then conform, approximately, to the shape of the tip of the wick-tube.

Instead of connecting the deflector to a burner, I may connect it to achimney or other analogous device which is used with a burner.

IOO

Although this improvement is especially intended for burners in whichkerosene-oil is used, it may be embodied in a burner in which any otheroil or fluid or even gas is used. In all cases the opening in thedeflector is to conform to the tip of the wick-tube or other burner-tube.

\Vhat I claim as my invention, and desire to secure by Letters Patent,is

1. The combination, with a burner, of adefleetor having a centralopening conforming in shape to the tip of the burner-tube, and a flangeor petticoat extending downwardly therefrom, and provided with notchesor openings, substantially as specified. 2. The combination, with aburner, of a deflector having a central opening conforming in shape tothe tip of the burner-tube, and a flange or petticoat extendingtherefrom downwardly and toward the burner-tube, and provided withnotches or openings, substantially as specified.
